One of the last things we did in 2016 was to burn a bunch of old instrument boxes. In cleaning out the attic, we found a bunch of old height gauges and micrometers. Unfortunately, many of them had irreparable rust on them so they went off to scrap and the usable ones went to Eva's office where they actually use that type of thing.
After scrapping the bad ones we had a lot of wooden boxes that were impregnated with machine oil from years of use and also very dry from being in the attic. As you'd expect, they burned very quickly. That's also an old, pipe-framed picnic table for scale.
